- Here is some pics of my two CGI blocks. The one with the billet main caps are bought from Tom. The other one is ready and fitted in my Focus RS now. In this block I use standard main caps and a lightened, balanced nitrided crank with teflon crank scrapers and oil squirters. CP Pistons (86mm
bore), Crower rods, ARP bolts and ACL Race bearings. Sorry for all pics... ;)
